Extensible markup language (XML) performance optimization on a multi-core central processing unit (CPU) through core assignment

Abstract

Embodiments of the present invention address deficiencies of the art in respect to XML schema validation and provide a method, system and computer program product for optimized XML schema validation and XML document parsing. In one embodiment, an XML data processing system can include shared memory; an XML co-processing proxy comprising program code enabled to receive at least one of XML document schema validation and XML document parsing requests from client applications, and at least one XML processing element coupled to the shared memory. In particular, the XML processing element can be configured to perform the at least one of the XML schema validation and XML document parsing on XML documents provided by the XML co-processing proxy. The XML processing element further can be configured to place results of XML schema validation or the XML document parsing in the shared memory.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to Extensible Markup Language (XML) parsing and schema validation, and more particularly to the use of separate processing appliances to perform XML parsing and schema validation.[0003]2. Description of the Related Art[0004]The Extensible Markup Language (XML) is a markup language specification widely credited with improving the functionality of the World Wide Web by allowing the identification of information in a more accurate, flexible, and adaptable way. XML is referred to as “extensible” because XML is not a fixed format like the hypertext markup language (HTML) which is a single, predefined markup language. Rather, XML is a meta-language that describes other languages. As such, XML allows for the design of other markup languages for limitless different types of documents. XML can act as a meta-language because XML is written according to the standardized general markup language (SGML)—...

Benefits of technology

The present invention provides a method, system, and computer program product for optimized XML schema validation. The invention addresses deficiencies in the art by improving the process of validating XML documents. The method includes placing an XML document in shared memory and processing it using an XML processing element operating within a CPU core. The results of the processing are then retrieved from the shared memory. The invention also includes queuing pointers to results, detecting a threshold number of pointers, and forwarding a notification to retrieve the results. Additionally, the invention includes assigning functionality to a generalized core CPU so that it will process the XML document in shared memory. The invention also includes detecting when the XML schema validation process falls out of scope and directing the XML processing element to discontinue processing the XML document. The system includes shared memory and an XML co-processing proxy coupled to the shared memory, with an XML processing element for performing XML schema validation. The system can also include a multi-core CPU or a symmetric multi-processing (SMP) architecture for supporting the XML processing elements. The technical effects of the invention include improved efficiency and accuracy in XML schema validation.

Problems solved by technology

As it will be apparent then to the skilled artisan, the validation process can be resource consuming in nature.

Yet, significant overhead remains in the packaging and communication of the XML document between the application and the XML processing appliance.
